<H2>flatten</H2>
<HR>
Flatten edit cell into the indicated destination cell.
<HR>

<H3>Usage:</H3>
   <BLOCKQUOTE>
      <B>flatten</B> <I>cellname</I> [<I>option</I>] <BR><BR>
      <BLOCKQUOTE>
         where <I>cellname</I> is the name of a cell definition to be
	 created, and into which the flattened geometry will be placed.
	 <I>option</I> may be one of <B>-nolabels</B>, <B>-nosubcircuit</B>,
	 or <B>-novendor</B>.
      </BLOCKQUOTE>

<H3>Summary:</H3>
   <BLOCKQUOTE>
      The <B>flatten</B> command creates a new cell with the indicated
      name, then flattens the hierarchy of the current edit cell and
      copies the result into the new cell. <P>

      The options allow selective flattening, as follows:
      <DL>
        <DT> <B>-nolabels</B>
        <DD> Prevents magic from copying labels into the flattened cell.
	     Otherwise, magic flattens labels by prepending the cell
	     hierarchy to each label as it copies it into the flat cell.
        <DT> <B>-nosubcircuit</B>
	<DD> Prevents magic from flattening cells declared to be subcircuits
	     (by the presence of ports in the cell).  These cells are
	     retained as subcells in the flattened version.
        <DT> <B>-novendor</B>
	<DD> Prevents magic from flattening cells that are vendor cells,
	     that is, cells that are generated by reading GDS using the
	     <B>gds readonly</B> option, or which have the appropriate
	     property values set.

      </DL>

      Note that <I>cellname</I> is a top-level cell but is not displayed
      or saved subsequent to the <B>flatten</B> command.  The usual
      procedure is to follow the command "<B>flatten</B> <I>cellname</I>"
      with "<B>load</B> <I>cellname</I>", to view the new flattened
      layout.

<H3>Implementation Notes:</H3>
   <BLOCKQUOTE>
      <B>flatten</B> is implemented as a built-in command in <B>magic</B>.
